Correct Answer: D

Rationale: The major characteristic of a cardiac malformation associated with left-to-right shunting is increased blood flow to the lungs. This increased flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a typical characteristic of this condition. Severe growth retardation (Choice B) is not directly associated with left-to-right shunting. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions involving chronic hypoxia.

Correct Answer: A

Rationale: The passage of a normal brown stool in a child with intussusception could indicate spontaneous reduction of the intussusception. This change in the patient's condition is significant, requiring prompt notification of the practitioner for further evaluation and management. While measuring abdominal girth (Choice B) is important for assessing abdominal distention, it is not the priority when a potential spontaneous reduction may have occurred. Auscultating for bowel sounds (Choice C) and taking vital signs, including blood pressure (Choice D), are routine nursing assessments but do not address the immediate need to inform the practitioner of a possible change in the patient's condition that necessitates urgent attention.

Correct Answer: D

Rationale: Negativism in toddlers commonly occurs around the age of 2 as they begin to assert their independence and autonomy. At this stage, children are exploring their own will and preferences, leading to behaviors like defiance or negativism. Independence (choice D) is the primary need being met by this behavior as toddlers strive to establish their individuality and decision-making. While trust (choice A) is crucial for forming secure attachments, it is not the main need driving negativism in this case. Seeking attention (choice B) may be a behavior exhibited by children, but it is not the fundamental need being fulfilled by negativism. Discipline (choice C) is important for setting boundaries and teaching appropriate conduct, but it is not the primary need being addressed by negativism in toddlers.

Correct Answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.

Correct Answer: C

Rationale: The correct clinical manifestation the healthcare provider is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception involves one portion of the intestine telescoping into another, causing obstruction. Abdominal distension is a common symptom due to the obstruction and buildup of gas and fluid in the affected area. While projectile vomiting can occur, it is not as specific to intussusception as abdominal distension. Currant jelly stools, which are stools containing blood and mucus, are a classic sign of intussusception but are not a clinical manifestation observable on assessment. Constipation is not typically associated with intussusception, as this condition often presents with symptoms of bowel obstruction rather than constipation.
